WALCOTT (Charles P.)— Continued 



The geiuis occupies an intermediate position between Dikelocephalus and Ptychoparia, 

 characterized by its elongated palpebral lobes, narrow free cheeks and elongated gla- 

 bella, narrowing more or less slightly towards the broadl\ rounded front. 



The Chinese species are: Conokeplinltna vesta Wale, C. heliis Wale, C. dryope 

 Wale, C. inaia Wale, and C. sp. undt. 



Genus Crepicephalus, Owen, 1852. Oenotype C. lo-zvetisis Owen. 



Crep'nepluilus Jamia Wale. This species, which is nearly related to C. lo^censis, 

 differs by the form of the frontal limb and rim of the glabella and other details. 



^7. coni'exus Wale, and C. wagniis Waic. 



Genus Lonchocephalus Owen, 1852. Genotype L. Iitimuliis Owen. 



The author refers the Ptychopariu ielliis Wale, 19(i5, to this genus. 



Genus Liostracina Monke, 1903. Genotype /.. kniusci Monke. 



Genus Proampyx Freeh, 1902. Cienotype Aiiomocare acuminatum Ang. 



Walcott remarks that Dr. Freeh appears to haxe overlooked the fact that the spine 

 of the genus Ampyx is a spinose extension of the front of the glabella, while the nasute 

 projection of the frontal rim of Aiiomocnre acuminatum is from an entirely different 

 division of the head. 



Proampyx hnrea Wale 



Genus Pterocephalus Roemer, 1852. Genotype P. sancti-sahae Roemer. 



The author describes Pterocephalus asiaticus Wale, P. husiris Wale and P. liclies 

 all from fragments of the head and tails. 



Genus Shantungia Walcott, 1905. Genotype S. spinifera Wale 



The genus is characterized by the large palpebral lobes, nearly smooth truncate- 

 conical glabella, and the long, spinose extension of the front, which is unlike that of 

 Ampyx, as the latter proceeds from the glabella; while the spine of Shantungia is 

 from the frontal rim, in the same manner as that of Proampyx acuminatum Aug., but 

 differs in the character of the glabella and palpebral lobes. 



The only species described is that of the type. 



Genus Inouyia Walcott, 1911. 



The species referred to this genus have a swollen, tumid frontal limb; small pal- 

 pebral lobes; a convex subrectangular glabella; strong dorsal furrows about the gla- 

 bella, and marked glabellar furrows. 



Genotype Agraulos Capax Wale, 1906. In addition to the type the author describes 

 Inouyia aharis Wale, /. f acalle Wale, /. ? armata Wale, /. Jii'i Wale, /. ? in f lata 

 Wale, /. melie Wale, I. ? regularis Wale, /. tliisbc Wale and /. tiliana. 



Genus Agraulos Corda, 1847. 



The author refigures the type of the genus and describes the following: 



Agraulos ahrota Wale, .-/. dirce Wale, ./. dolou Wale, A. dryas Wale, A. nitida 

 Wale, A. ohscura Wale, A. sorgc Wale, A. uta Wale, and A. vicina Wale 



Genus Pagodia Walcott, 1905. CJenotype /■■. lotos Wale 



The author remarks that the genus differs from Dolichometopus and from the type 

 in the narrowing instead of widening of the glabella in front, in the presence of small 

 instead of large eye-lobes, short instead of long postero-lateral limbs and obscure gla- 

 bella furrows. 



The species referred to this genus are Pagodia hia, P. dolon, P. lotos and /*. macrdo 

 Walcott. 



Genus Lisania Walcott, 1911. Genotype Anomocarella ? bura Wale 



The species referred to the genus are all small, represented by cranidia and asso- 

 ciated free cheeks and pygidia. 



Lisania agonius Wale, L. ajax Wale, L. alala Wale, L. belemus, L. Intra Wale and 

 L. cf. bura Wale
